IEC 60598-2-18:2022

Overview

IEC 60598-2-18:2022 is the third edition of the international standard establishing particular requirements for luminaires designed specifically for swimming pools and similar water-related applications. Published by the International Electrotechnical Commission (IEC), this standard covers fixed luminaires intended for use in water or in contact with water, such as in swimming pool basins, fountains, paddling pools, and garden pools. It applies to luminaires that use electric light sources, including both traditional filament lamps and modern LED sources.

This standard replaces the previous edition from 1993 and its 2011 amendment, updating technical requirements to align with current lighting technologies and installation practices. It provides comprehensive guidance on luminaire construction, testing, marking, electrical protection, and waterproofing to ensure safe and reliable operation in wet environments.

Key Topics

• Scope and Application
  IEC 60598-2-18:2022 specifies requirements for fixed luminaires designed for continuous or intermittent immersion or contact with water in recreational and decorative aquatic installations. Hand-held or portable devices and luminaires not directly in contact with water are excluded.

• Classification and Safety
  Luminaires must be classified as Class III electrical devices, operating at low voltages not exceeding 12 V AC or 30 V DC ripple-free, to minimize the risk of electric shock.
  The ingress protection (IP) ratings require parts immersed in water to achieve IPX8 (pressure watertight), while parts outside water must have at least IP54 (dustproof and splashproof).

• Marking and Identification
  Updated marking requirements ensure clear identification of product safety attributes, including voltage class and protection degree, to support safe installation and maintenance.

• Construction and Materials
  Luminaire design must provide robust construction resistant to water pressure, corrosion, and environmental stresses typical of aquatic environments. Special consideration is given to creepage distances, clearances, and earthing provisions.

• Wiring and Cable Requirements
  External and internal wiring specifications have been aligned with IEC 60598-1 standards. The use of alternative waterproof multi-core cables conforming to relevant regional standards (such as EN 50525-2-21:2011) is permitted, addressing the need for data transmission suitability especially in LED luminaires with bus controls.

• Testing and Endurance
  The standard mandates rigorous tests including endurance, thermal, insulation resistance, electric strength, and resistance to dust, moisture, heat, fire, and tracking to ensure product durability and safety under operational conditions.

Applications

IEC 60598-2-18:2022 is essential for manufacturers, designers, and safety assessors involved with lighting solutions in:

• Swimming Pools – Ensuring lighting fixtures are safe, reliable, and durable under constant or periodic water immersion and chemical exposure.
• Fountains and Water Features – Providing requirements for decorative lighting used in fountains or garden water installations, where exposure to splashing and environmental moisture is common.
• Paddling Pools and Garden Pools – Specifying safety and construction criteria for luminaires used in shallow or decorative pools.
• Aquatic Recreational Facilities – Guiding the design and installation of illumination systems in complex wet environment settings where compliance with electrical safety standards is critical.

• IEC 60364-7-702: Electrical installations in swimming pools and fountains, detailing installation safety rules specific to wet locations.
• EN 50525-2-21:2011: Standard for low voltage flexible cables, referenced for acceptable cable types suitable for waterproof and data transmission purposes in luminaires.

Practical Value

Adhering to IEC 60598-2-18:2022 ensures luminaires used in aquatic environments meet rigorous safety, performance, and durability standards. This reduces risks of electrical hazards, enhances product reliability, and aligns with international best practices. The updated inclusion of LED technology and flexible cabling options reflects evolving lighting trends, supporting innovation while maintaining high safety levels. Compliance with this standard supports manufacturers in meeting global regulatory demands and facilitates market access for swimming pool and water feature lighting products worldwide.
